Architools and having to rekey serial number each time open Carrara? Help

So I bought Architools the other day --and have to say is a lot more to it then I thought ------but am having an issue of having to rekey my serial number each time I run (open) Carrara. Anyone have that issue ? I am using it with C8.112 pro.

yes --Jay your right. Julien got back to me to tell me to download from their site as daz's are older. So it works great now.
thanks--

btw Architools is pretty nifty.

I got addicted to it a few years ago when I first got it, kept putting together houses modeled after houses in my neighborhood, figuring out ways to do things, it was a lot of fun, and surprisingly you can make almost anything, with pretty decent accuracy too.
